The actual core is quite strictly Harvard now, treating the external RAM banks more like mass storage devices than an actual combined code+data memory. > Absolutely. But from the user viewpoint, it is the ISA that matters - That depends rather a lot on who gets to be called the "user". x86 are quite strictly limited to the PC ecosystem these days: boxes and laptops built for Mac OS or Windows, some of them running Linux instead. There the "user" is somebody buying hardware and software from completely unrelated suppliers. I.e. unlike in the embedded world we discuss here, the persons writing software for those things had no say at all what type of CPU is used. They're thus not really the "user." If they were, they probably wouldn't be using an x86. ;-) The actual x86 users couldn't care less about the ISA --- the overwhelming majority of them haven't the slightest idea what an ISA even is. Some of them used to have a vague idea that there was some 32bit vs. a 64bit whatchamacallit somewhere in there, but even that has surely faded away by now, as users no longer even face the decision between them.
